For the nicer reliability, Hough transformation is used very broad in the area of digital image manipulation. But the transformation has some disadvantages, such as too much memory space, complex calculation and long disposal time. After analyzed the Hough transformation and some other improved methods and the geometry characteristics of the rotundity, a new method of rotundity recognition was put forward, which is called Single Parameter Hough Transformation(SPHT) and used to detect the image of circularity.
